The win object of this invention is to} provide a table for stone cutters which may be tilted in any direction so that inclinedor leveled faces may be formedby the hammer upon a block of stone.

Another object of the invention to provide .a stone cutters table 'which is con-' structed in such manner as to permit the I table proper to be adjusted to any degree of inclination within predetermined limits by the rotation of table. a

The above and other objects will become apparent in the description below in which characters of reference refer to like-named Referring briefly to the drawings'pFigure 1 is a side elevational view of the leveling table. 7 v

Figure 2 is a top plan viewof the same. Referring in detail to the drawings, the

numeral 10 indicates a base upon which a turn surmounted by, a ball 12 which registers I in a hemispherical socket 130i an inverted 1 bell 14. The bell is formed integral with an ends of a rotatable spindle 22. I

able spindle passes throughthe beams 16 pedestal 11 is mounted. This pedestal is in apron 15,the latterbeing secured to a pair 0 spaced apart beams 16 and 17 :The beams 16 and 17 support table boards 17 upon which rest slats 19; these slats being used for the purpose of resting such articles of work as a stone slab which is to be worked or suri'aced. The table 18 on its ends is providedwith a pair of brackets 20 and 21, one -.at" each end. The brackets are suspended from the under side of said table and journal the Said rotatand 17' and is journaled therein intermediate its length. One end of the spindle 22 lying adjacent the bracket 21 hasa worm gear 23 1 mounted thereon which meshes witha Worm 24L. Said worm has oneend journalled in an'ear 25 and extends toward the side;of the table. The projecting end 26 of the worm shaft 27 is squared so that a wrench or crank handle may be applied thereto, when it is desired to rotate the member 22." Adjacent the worm gear 23, the end 27 of a cable 28 is woundabout the spindle 22 for a few turns.

Thiscable is suspendedtangentially from one I side of the spindle 22 andsecured 'ata of the device. Near the'opposite end of the spindle 22 a second cable 29 is secured to the spindle andis trained a few turns about convenient position to the support surface I the same and suspends tangentially from the- I opposite side of thespindle so that as the; cable 28 takes up the cable29'pays' out. Thisl f i "arrangement will permit inclination ofthe table 18 in one direction. Asecond auxil- .iary spindleBO- is journaledin brackets 31. e. r These brackets arearranged at opposite sides r I of the table and depend from the latter.

'N ear one end of the auxiliary spindle 30'. a 'Worm gear 32 is mounted. This worm gear meshes with a second worm 33 to one end of which isattached a chain wheel 3twhich is.

pair of cables 86 and 37 are-suspended tangentially from opposite sides of the auxiliary, spindle 30. 2'

e The device is adapted toincline the table in either direction. When rotatingthe'worm shaft 27, the table is tilted in one direction through the medium of the worm" gear 23 turnin the spindle 22. The table will shift upon the ball .12 when this occursand will clined position, By rotating the chain wheel "34, the auxiliary spindle 30 is rotated, thus inclining the table in the other direction.

7 It is to be noted that certain changes in form and construction may be made without departing from the spirit and scope of the invention. 1 Y i I claim:
